1A wheel starts from rest and reaches an angular velocity of 12 rad/s in 4.0 s under constant angular acceleration. What is its angular acceleration?
A.3.0 rad/s^2
B.0.33 rad/s^2
C.48 rad/s^2
D.8.0 rad/s^2
Explanation: Use omega = omega_0 + alpha t with omega_0 = 0. alpha = omega / t = 12 / 4.0 = 3.0 rad/s^2.
2A flywheel rotates at 50 rad/s and decelerates uniformly to rest in 25 s. Through what angle (in radians) does it turn during this deceleration?
A.625 rad
B.1250 rad
C.312 rad
D.100 rad
Explanation: Use theta = (omega_0 + omega)/2 * t = (50 + 0)/2 * 25 = 25 * 25 = 625 rad.
3A point on the rim of a disc of radius 0.20 m moves with tangential speed 6.0 m/s. What is the angular velocity of the disc?
A.30 rad/s
B.1.2 rad/s
C.0.033 rad/s
D.12 rad/s
Explanation: v = r * omega, so omega = v / r = 6.0 / 0.20 = 30 rad/s.
4A car of mass 1200 kg travels around a curve of radius 50 m at 15 m/s. What is the magnitude of the centripetal force required?
A.5400 N
B.360 N
C.180 000 N
D.1080 N
Explanation: F = m v^2 / r = 1200 * 15^2 / 50 = 1200 * 225 / 50 = 270000 / 50 = 5400 N.
5A conical pendulum has a string of length 1.0 m making an angle of 30 degrees with the vertical. What is the period of the motion? (g = 9.8 m/s^2)
A.1.87 s
B.2.01 s
C.0.93 s
D.3.14 s
Explanation: For a conical pendulum T = 2*pi*sqrt(L*cos(theta)/g) = 2*pi*sqrt(1.0*cos30/9.8) = 2*pi*sqrt(0.866/9.8) = 2*pi*sqrt(0.0884) = 2*pi*0.297 = 1.87 s.
6A car travels over a hump in the road. At the top of the hump, what condition gives the maximum speed at which the car remains in contact with the road?
A.mg = m v^2 / r
B.Normal force N = mg
C.v = sqrt(2 g r)
D.N = 2 m g
Explanation: At the top of the hump the centripetal force is provided by gravity minus the normal force: mg - N = m v^2 / r. The car leaves the road when N = 0, giving mg = m v^2 / r and so v = sqrt(g r).
7A car of mass 1000 kg goes around a banked track of radius 80 m. The track is banked at 20 degrees so that no friction is required at the design speed. What is the design speed? (g = 9.8 m/s^2)
A.16.9 m/s
B.27.2 m/s
C.11.7 m/s
D.4.7 m/s
Explanation: For a banked track with no friction, tan(theta) = v^2 / (r g). So v = sqrt(r g tan(theta)) = sqrt(80 * 9.8 * tan20) = sqrt(80 * 9.8 * 0.364) = sqrt(285.4) = 16.9 m/s.
8Which expression gives the moment of inertia of a uniform solid sphere of mass m and radius r about a diameter?
A.(2/5) m r^2
B.(1/2) m r^2
C.(2/3) m r^2
D.m r^2
Explanation: A uniform solid sphere has I = (2/5) m r^2 about a diameter through its centre — listed in the SQA data sheet.
9A disc of moment of inertia 0.40 kg m^2 rotates at 20 rad/s. What is its rotational kinetic energy?
A.80 J
B.160 J
C.40 J
D.8.0 J
Explanation: KE_rot = (1/2) I omega^2 = 0.5 * 0.40 * 20^2 = 0.5 * 0.40 * 400 = 80 J.
10A figure skater with arms outstretched has moment of inertia 4.0 kg m^2 and spins at 2.0 rad/s. She pulls her arms in, reducing her moment of inertia to 1.0 kg m^2. What is her new angular velocity?
A.8.0 rad/s
B.0.5 rad/s
C.2.0 rad/s
D.16 rad/s
Explanation: Angular momentum is conserved: I_1 omega_1 = I_2 omega_2. So omega_2 = (4.0 * 2.0) / 1.0 = 8.0 rad/s.

Advanced Higher Physics: Suggested Study Strategy

1Work through past papers from Qualifications Scotland — the question style is highly consistent year on year
2Memorise key equations not provided in the data sheet, especially those for rotational dynamics and capacitor/inductor circuits
3Practise propagation of uncertainty for the project; it is heavily marked and frequently lost
4Use marking instructions to learn the specific language examiners expect for derivation and explanation marks
